Claims. (01. 22.7-12.3)

My invention relates to an appliance for hanmay be provided with the cooling fan 8, for cooldling air for engines and the automobile aeroing the parts of the generator. planes, boats or other things which may have The suction inlet 9 is provided with the barrel engines, and has among its objects to provide: valve I0, operated by the lever H, and is open 5 A fan or blower which may be conveniently at its inner end l2. The valve l0 revolves in its and quickly connected to supercharge the engine, casing l3, to which the intake heater, pipe It a blow off dust, vacuum clean and heat the car is secured and connects with the port of said as well as air to carburetor and defrost the windvalve when it is desired to pass heated air shield or other windows. through said pipe M from the stove 16 around :0 A convenient car heating and cleaning device. the exhaust manifold or pipe I! of the engine' 10 A system of conveniently arranged and operl8 to the blower ated valves to handle low pressure cool or heated The blower delivers the heated air through its air. discharge outlet l9 to the discharge valve 20, A car piping system for air. which is open at its inner end 2| to communicate A blower which may quickly be adapted to with the discharge outlet I9. The valve 20 is fig numerous applications of air for cleaning, heatprovided with the port 22 which communicates ing, defrosting and supercharging. with the bypass pipe 23 which is connected to I accomplish these and other objects by the the housing 24 on which said valve 20 rotates. construction herein described and shown in the The bypass pipe is provided with the pipe 25 20 co p g drawings in which: which connects said blower l with the interior go 1 s a eneral ele a on of a p t Of an of the car 26 where several outlets 21 are proalltomObile Showing e pp ic of y d vided to deliver heated air for heating the car.

My blower valves and piping make an buIetO! a increased use of these labor saving, convenient A movement of the valves in and 20 pp o and meritorious devices 'mately 90 degrees, causes the port l5 to connect I have herein shown my preferred form which the bypass P p 23 w t the b ower in ake or 4 may be modified to suit varying conditions such suction inlet 9, thus changing the flow from as the arrangements of the parts of the motor heated air under pressure to cold air under a and its use as in a car, plane, or boat, etc. The vacuum in the pipe 25 and the ports 22 and 34 fan or blower l, is so driven by the fan belt 2 of the discharge valve housing 24 are closed so as shown in Figure 1, or' directly connected to while the port 35 is-open to the discharge outlet the generator or motor 2 as shown in ,Figure 2, IQ of the blower I. I where the blower rotor 3 is mounted on the The port 35 connects to the discharge nozzle armature shaft 4. The rotor and its blades 5 36, permitting dirt and air from the vacuum are mounted in the blower housing 13, secured cleaning nozzle 31 to escape therethrough. to the generator 2'-by the framework l' which The vacuum cleaner is preferably attached by its flexible hose 38 to the outlets 21 in the usual manner with vacuum systems.

When it is desired to blow cold air through the pipe 25, the pipe l4 may be provided with a valve 39 suitable to shut oil the air from the stove and open the cold air inlet 40.

The valves l0 and 20 are preferably operated simultaneously by means of the detachable link l4 connecting the lever II and the lever 42 of the valve 20. The link 4i is preferably provided with the pins 43 and 44 at each end which are provided with the side grooves 45 adapted to receive the hairpin springs 46. A 90 degree turn of said pins forces said springs out of their notches, permitting the free withdrawal of the pins and the link.

Upon removal of the link 4|, each of the levers H and 42 may be operated independently.

For the purpose of simplicity and clarity, I have shown and described but one of the various constructions herein and I may wish to depart from these details as my device may be modified to suit its various uses and applications within the scope of the appended claims which succinctly set forth my invention.
